DETAILED DESCRIPTION

Specific details of several embodiments of the present technology are disclosed herein with reference to FIGS. 1-20 b. It should be noted, in general, that other embodiments in addition to those disclosed herein are within the scope of the present technology. For example, embodiments of the present technology can have different configurations, components, and/or operations than those disclosed herein. Moreover, a person of ordinary skill in the art will understand that embodiments of the present technology can have configurations, components, and/or operations in addition to those disclosed herein and that these and other embodiments can be without configurations, components, and/or operations disclosed herein without deviating from the present technology.

FIGS. 1 and 2 are an isometric view and an exploded isometric view, respectively, of a modular wall 100 in a first state in accordance with at least some embodiments of the present technology. With reference to FIGS. 1 and 2 together, the modular wall 100 can include units configured to be assembled with one another in a stacked and interlocking arrangement. In at least some cases, the units are configured to stack and to interlock without the use of tools. Among the units, the modular wall 100 can include main units 102 (individually identified as main units 102 a-102 r) arranged in horizontal rows 104 (individually identified as rows 104 a-104 d). Seams 106 (one labeled in FIG. 1) between the main units 102 in a given one of the rows 104 can be horizontally staggered (e.g., evenly offset) relative to the seams 106 in the row or rows 104 vertically neighboring the given row. The modular wall 100 can also include cap units 108 (individually identified as cap units 108 a-108 j) arranged in a row overlying the rows 104, and base units 110 (individually identified as base units 110 a-110 j) arranged in a row underlying the rows 104. For clarity of illustration, the horizontal spacing in FIG. 2 between the cap units 108, between the base units 110, and within the rows 104 is not uniform. When the modular wall 100 is fully assembled on a flat surface (not shown), it can be self-supporting and free-standing.

As shown in FIG. 1, the modular wall 100 can be L-shaped, and can have a first end portion 112, a second end portion 114, and a corner portion 116 therebetween. Due to the horizontal staggering of the seams 160, the main units 102 in the rows 104 b, 104 d can form insets at the first end portion 112 and at the second end portion 114. At these insets, the modular wall 100 can include end units 118 (individually identified as end units 118 a-118 d). The end units 118 can be configured to fill the insets such that the modular wall 100 is straight rather than staggered at the first end portion 112 and at the second end portion 114. When straight end portions are not needed, the end units 118 can be omitted. Similarly, when finished bottom and/or top portions are not needed, the cap units 108 and/or the base units 110, respectively, can be omitted. Furthermore, the main units 102, the cap units 108, the base units 110, and the end units 118 can be arranged to form shapes other than L-shapes. For example, the main units 102 a, 102 b, 102 f, 102 j, 102 k, 102 o, the cap units 108 a-108 c, the base units 110 a-110 c, and the end units 118 a, 118 c can be collectively rotated 90 degrees about a vertical axis and assembled with the other units of the modular wall 100 in a straight line. As another example, the main units 102 b, 102 g, 102 k can be arranged to project from the corner portion 116 in three different respective directions and interconnected with other units to form a T-shaped junction. As another example, the main units 102 b, 102 g, 102 k, 102 p can be arranged to project from the corner portion 116 in four different respective directions and interconnected with other units to form a cross-shaped junction. Furthermore, a greater or lesser number of rows 104 can be used to change the height of the modular wall 100 in any of its potential shapes. Also, a greater or lesser number of main units 102, cap units 106, and base units 108 can be used to change a length of any portion of the modular wall 100 in any of its potential shapes. This versatility and/or the ease of assembling and disassembling the modular wall 100 in its illustrated shape and other shapes can be particularly useful for temporary and/or dynamic installations.

FIGS. 3 and 4 are an isometric view and an exploded isometric view, respectively, of the main unit 102 i. In at least some cases, the individual main units 102 have the same construction and are interchangeable with one another. Accordingly, the same reference numbers used herein to identify portions of the main unit 102 i may also be used herein to identify corresponding portions of main units 102 other than the main unit 102 i. With reference to FIGS. 3 and 4 together, the main unit 102 i can include a shell 120, a reinforcing insert 122, and couplers 124 (individually identified as couplers 124 a-124 l) detachably coupled to one another. As parts of the shell 120, the main unit 102 i can include a first face panel 126, a second face panel 128 parallel to and spaced apart from the first face panel 126, a first side panel 130, and a second side panel 132 parallel to and spaced apart from the first side panel 130. The first face panel 126, the second face panel 128, the first side panel 130, and the second side panel 132 can be detachably connected to one another via the couplers 124 a-124 h.

In at least some cases, the main interior volume 134 is shaped as a rectangular solid. The main unit 102 i can further include a first flange 136 carried by and inwardly positioned relative to the first face panel 126, and a second flange 138 carried by and inwardly positioned relative to the second face panel 128. The main unit 102 i can also include a first slot 140 and a second slot 142 defined by the first flange 136 and the second flange 138, respectively. The first flange 136 and the second flange 138 can protrude vertically from the main interior volume 134 of the main unit 102 i such that the first slot 140 and the second slot 142 are outside the main interior volume 134 of the main unit 102 i. With reference to FIGS. 1-4 together, the first slot 140 and the second slot 142 of a given one of the main units 102 (e.g., main unit 102 i) can be positioned to receive respective portions of the first side panel 130 of a first vertically neighboring one of the main units 102 (e.g., main unit 102 n) and the second side panel 132 of a second vertically neighboring one of the main units 102 (e.g., main unit 102 m).

One, some, or all of the main unit 102 i, the shell 120, the reinforcing insert 122, the couplers 124, the first face panel 126, the second face panel 128, the first side panel 130, the second side panel 132, the first flange 136, and the second flange 138, individually, can be made at least primarily (i.e., at least 50% by weight) of one or more pieces cut from one or more sheet materials. Examples of sheet materials include wood-based sheet materials (e.g., plywood, medium-density fiberboard, high-density fiberboard, oriented strand board, particle board, hardboard, etc.), plastic sheet materials (e.g., polyethylene, polypropylene, polycarbonate, polystyrene, polyvinyl chloride, acrylonitrile butadiene styrene, etc.), gypsum board, and cement board. Among sheet materials, cement board is particularly well suited for use in at least some embodiments of the present technology. Cement board includes cementitious binder (e.g., calcium silicate based cement) and, optionally, other materials, such as sand, cellulose, and glass fibers. One example of a cement board well suited for use in at least some embodiments of the present technology is HARDIEBACKER® 500 cement board available from James Hardie Building Products (Chicago, Ill.).

As shown in FIG. 5, when detached from one another, the first face panel 126, the second face panel 128, the first side panel 130, the second side panel 132, and the couplers 124 a-124 h can be packed together in a compact arrangement well suited for shipping. FIGS. 6a and 6b are isometric views of the first face panel 126 and associated portions of the main unit 102 i taken from different respective angles. FIGS. 7a and 7b are isometric views of the first side panel 130 and associated portions of the main unit 102 i taken from different respective angles. In at least some cases, the first face panel 126 and the second face panel 128 have the same construction and are interchangeable with one another. Similarly, the first side panel 130 and the second side panel 132 can have the same construction and be interchangeable with one another. Accordingly, the same reference numbers used herein to identify portions of the first face panel 126 may also be used herein to identify corresponding portions of the second face panel 128 and vice versa. Also, the same reference numbers used herein to identify portions of the first side panel 130 may also be used herein to identify corresponding portions of the second side panel 132 and vice versa.

With reference to FIGS. 1-7 b together, the first face panel 126, the second face panel 128, the first side panel 130, and the second side panel 132, individually, can have a first horizontal edge portion 146, a second horizontal edge portion 148 vertically spaced apart from the first horizontal edge portion 146, a flat inner surface 150, and a flat outer surface 152. The first flange 136 can overlap the second horizontal edge portion 148 of the first face panel 126. Similarly, the second flange 138 can overlap the second horizontal edge portion 148 of the second face panel 128. The first flange 136 and the second flange 138, individually, can have a flat inner surface 154 and a flat outer surface 156. The outer surface 156 of the first flange 136 can be in the same vertical plane as a portion of the inner surface 150 of the first face panel 126 at the first horizontal edge portion 146 of the first face panel 126. Similarly, the outer surface 156 of the second flange 138 can be in the same vertical plane as a portion of the inner surface 150 of the second face panel 128 at the first horizontal edge portion 146 of the second face panel 128. The first slot 140 can have sides defined by the first flange 136, and an end defined by the second horizontal edge portion 148 of the first face panel 126. Similarly, the second slot 142 can have sides defined by the second flange 138, and an end defined by the second horizontal edge portion 148 of the second face panel 128. A width of the first slot 140 in a plane parallel to the first face panel 126 can be from 100% to 125% of a sum of a thickness of the first side panel 130 and a thickness of the second side panel 132. Similarly, a width of the second slot 142 in a plane parallel to the second face panel 128 can be from 100% to 125% of the sum of a thickness of the first side panel 130 and a thickness of the second side panel 132. Furthermore, the first slot 140 and the second slot 142 can be in a vertical plane within 10% of being equally spaced between the first side panel 130 and the second side panel 132. These and other features of portions of the main unit 102 i can facilitate forming interlocking connections between the main unit 102 i and the cap units 108, between the main unit 102 i and the base units 110, between the main unit 102 i and the end units 118, and between the main unit 102 i and the other main units 102 within the modular wall 100.

As shown in FIG. 5, the first flange 136 can include a first leaf 158 at one side of the first slot 140, and a second leaf 160 spaced apart from the first leaf 158 at an opposite side of the first slot 140.

The main unit 102 i can also include first insert-connecting hooks 168 (individually identified as first insert-connecting hooks 168 a-168 d) individually carried by one of the first face panel 126 and the second face panel 128. The first insert-connecting hooks 168 are discussed below with regard to the reinforcing insert 122.

FIG. 8 is an exploded isometric view of the reinforcing insert 122 (FIG. 4). FIG. 9 is an isometric view of a kit 170 for making the reinforcing insert of 122. FIG. 9 is an isometric view of a kit 170 for making the reinforcing insert 122 and for connecting the reinforcing insert 122 to the shell 120 (FIG. 4). With reference to FIGS. 1-9 together, as parts of reinforcing insert 122, the main unit 102 i can include a first interior panel 172 within the main interior volume 134 of the main unit 102 i, and a second interior panel 174 also within the main interior volume 134 of the main unit 102 i. The first interior panel 172 can be parallel to the first side panel 130 and to the second side panel 132, and can be in a vertical plane within 10% of being equally spaced between the first side panel 130 and the second side panel 132. In at least some cases, the first interior panel 172, the first slot 140, and the second slot 142 are in the same vertical plane. In these and other cases, the first interior panel 172 can have a thickness from 75% to 125% of a sum of a thickness of the first side panel 130 and a thickness of the second side panel 132. The second interior panel 174 can be perpendicular to the first interior panel 172, to the first face panel 126, to the second face panel 128, to the first side panel 130, and to the second side panel 132. When the main unit 102 i is assembled, the second interior panel 174 can be vertically supported by the first flange 136 and by the second flange 138.

FIGS. 10a and 10b are isometric views of the first interior panel 172 and associated portions of the main unit 102 i taken from different respective angles. With reference to FIGS. 1-10 b together, the first interior panel 172 and the second interior panel 174 can be detachably connected to the first face panel 126, to the second face panel 128, to the first side panel 130, and to the second side panel 132. The first interior panel 172 and the second interior panel 174 can also be detachably connected to one another. For example, the main unit 102 i can include a third slot 176 defined by the first interior panel 172 that slidably receives a portion of the second interior panel 174. Similarly, the main unit 102 i can include a fourth slot 178 defined by the second interior panel 174 that slidably receives a portion of the first interior panel 172. The main unit 102 i can also include second insert-connecting hooks 180 (individually identified as second insert-connecting hooks 180 a-180 d) carried by the first interior panel 172. The couplers 124 k, 124 l can be detachably connected to the first face panel 126 via the first insert-connecting hooks 168 a, 168 b, respectively, and detachably connected to the first interior panel 172 via the second insert-connecting hooks 180 a, 180 d, respectively. Similarly, the couplers 124 i, 124 j can be detachably connected to the second face panel 128 via the first insert-connecting hooks 168 c, 168 d, respectively, and detachably connected to the first interior panel 172 via the second insert-connecting hooks 180 c, 180 b, respectively.

At least some of the panel-connecting hooks 166 (FIGS. 6a and 7a ), the first insert-connecting hooks 168 (FIG. 6a ), and the second insert-connecting hooks 180 (FIG. 10a ) can have the same construction. Furthermore, at least some of the panel-connecting hooks 166, the first insert-connecting hooks 168, and the second insert-connecting hooks 180 can be made at least primarily of built-up pieces of sheet material (e.g., cement board). As one example, the second insert-connecting hook 180 a (FIG. 10a ) can include a projecting piece 182 and a connecting piece 184 sandwiched between the projecting piece 182 and the first interior panel 172. Likewise, the first interior panel 172 can be made at least primarily of one or more pieces of sheet material (e.g., cement board). As shown in FIGS. 10a and 10 b, the first interior panel 172 can include two subpanels 186 (individually identified as subpanels 186 a, 186 b) laminated together. The first interior panel 172 can further include stabilizing pieces 188 (individually identified as stabilizing pieces 188 a, 188 b) adjacent to the third slot 176 at opposite respective sides of the first interior panel 172. The stabilizing pieces 188 can be useful, for example, to stabilize a detachable connection between the first interior panel 172 and the second interior panel 174.

FIGS. 11a and 11b are isometric views of the coupler 124 a taken from different respective angles. In at least some cases, the individual couplers 124 have the same construction and are interchangeable with one another. This interchangeability and the other interchangeability discussed above with reference to other components of the modular wall 100 can be useful to simplify manufacturing and installation of the modular wall 100 and components thereof. The same reference numbers used herein to identify portions of the coupler 124 a may also be used herein to identify corresponding portions of couplers 124 other than the coupler 124 a. In at least some cases, the couplers 124 are configured to slidably connect to the corresponding ones of the panel-connecting hooks 166, the first insert-connecting hooks 168, and the second insert-connecting hooks 180. For example, the couplers 124 can be drop-in couplers and/or be otherwise configured to move vertically to detachably engage or disengage with the corresponding ones of the first face panel 126, the second face panel 128, the first side panel 130, the second side panel 132, and the first interior panel 172 via the corresponding ones of the panel-connecting hooks 166, the first insert-connecting hooks 168, and the second insert-connecting hooks 180.

As shown in FIGS. 11a and 11b , the coupler 124 a can include a plate 190, a first bracket 192 extending along one side portion of the plate 190, and a second bracket 194 extending along another side portion of the plate 190. The first bracket 192 and the second bracket 194 can be at a right angle relative to one another. In at least some cases, the plate 190 is shaped as a right triangle (e.g., an isosceles right triangle), and the first bracket 192 and the second bracket 194 extend along the legs of the right triangle, respectively. In these and other cases, the first bracket 192 and the second bracket 194, individually, can be L-shaped. Furthermore, the first bracket 192 and the second bracket 194 can individually be shaped to snugly receive the connecting pieces 184 (FIG. 10a ) of the panel-connecting hook 166 b and the panel-connecting hook 166 c, respectively, when the first face panel 126 and the first side panel 130 are abutting one another at a right angle. Similarly, the other couplers 124 can be configured to interact with the connecting pieces 184 of corresponding ones of the panel-connecting hooks 166, the first insert-connecting hooks 168, and the second insert-connecting hooks 180 to form right-angle connections between corresponding pairs of the first face panel 126, the second face panel 128, the first side panel 130, the second side panel 132, and the first interior panel 172.

FIGS. 12 and 13 are an isometric view and an exploded isometric view, respectively, of the end unit 118 a. In at least some cases, the individual end units 118 have the same construction and are interchangeable with one another. With reference to FIGS. 12 and 13 together, the end unit 118 a can include panels 196 (individually identified as panels 196 a-196 d) and couplers 198 (individually identified as couplers 198 a-198 h) through which the panels 196 are detachably coupled to one another. In at least some cases, the individual couplers 198 have the same construction and are interchangeable with one another and with the individual couplers 124 (FIG. 4). The end unit 118 a can further include flanges 200 (individually identified as flanges 200 a-200 d) carried by and inwardly positioned relative to the individual panels 196, respectively. The individual flanges 200 can be similar to the first leaf 158 of first flange 136 (FIG. 6a ), the second leaf 160 of first flange 136 (FIG. 6a ), the first leaf 162 of second flange 138 (FIG. 6b ), and the second leaf 164 of second flange 138 (FIG. 6b ), individually. The end unit 118 a can also include an interior panel 201 similar to the second interior panel 174 (FIG. 8). The interior panel 201 can be horizontal and supported by the flanges 200 when the end unit 118 a is assembled.

As mentioned above with reference to FIGS. 1 and 2, the end units 118 can be configured to fill insets associated with staggering of the main units 102. Accordingly, the lengths of the individual end units 118 parallel to the modular wall 100 can be half the lengths of the individual main units 102 parallel to the modular wall 100 when the main units 102 are configured to be evenly staggered. With reference to FIGS. 2, 12 and 13 together, the individual main units 102 can be configured to receive the flanges 200 of a vertically neighboring one of the end units 118. Similarly, the individual end units 118 can be configured to receive the second leaf 160 of the first flange 136 (FIG. 6a ) and the first leaf 162 of the second flange 138 (FIG. 6b ) of a vertically neighboring one of the main units 102 or the first leaf 158 of first flange 136 (FIG. 6a ) and the second leaf 164 of second flange 138 (FIG. 6b ) of a vertically neighboring one of the main units 102.

FIGS. 14 and 15 are isometric views of the base unit 110 a and the cap unit 108 a, respectively. In at least some cases, the individual base units 110 have the same construction and are interchangeable with one another. Similarly, the individual cap units 108 can have the same construction and be interchangeable with one another. As shown in FIG. 14, the base unit 110 a can include a five-sided shell 202 and parallel slats 204 (one labeled) within the shell 202. As shown in FIG. 15, the cap unit 108 a can similarly include a five-sided shell 206 and parallel slats 208 (one labeled) within the shell 206. The cap unit 108 a can further include flanges 210 (individually identified as flanges 210 a-210 d) projecting from the shell 206. The individual flanges 210 can be similar to the individual flanges 200 (FIG. 13). As shown in FIG. 2, the individual base units 110 can be configured to receive the flanges 200 of a vertically neighboring one of the end units 118, the second leaf 160 of the first flange 136 (FIG. 6a ) and the first leaf 162 of the second flange 138 (FIG. 6b ) of a vertically neighboring one of the main units 102 or the first leaf 158 of first flange 136 (FIG. 6a ) and the second leaf 164 of second flange 138 (FIG. 6b ) of a vertically neighboring one of the main units 102. The individual main units 102 and the individual end units 118 can be configured to receive the flanges 210 of a vertically neighboring one of the cap units 108.

FIG. 16 is a cross-sectional isometric view taken along the line A-A in FIG. 1 of the modular wall 100 in a first state in which the reinforcing inserts 122 of the main units 102 are present. In the first state, the main units 102 can carry a vertical load on the modular wall 100 evenly via the first face panels 126 (FIG. 4), the second face panels 128 (FIG. 4), the first side panels 130 (FIG. 4), the second side panels 132 (FIG. 4), and the first interior panels 172 (FIG. 9). FIG. 17 is a cross-sectional isometric view taken along the line A-A in FIG. 1 of the modular wall 100 in a second state in which the reinforcing inserts 122 of the main units 102 are not present. In the second state, the main units 102 can carry a vertical load on the modular wall 100 at least primarily via the first face panels 126 (FIG. 4) and the second face panels 128 (FIG. 4). In both the first state and the second state, the modular wall 100 can have significant load-bearing capacity. When the modular wall 100 is in the first state, however, this load-bearing capacity can be greater than when the modular wall 100 is in the second state. In at least some cases, it can be useful to assemble the modular wall 100 in the first state when there is a need for the modular wall 100 to support a significant load, such as from an associated ceiling (not shown) and to assemble the modular wall 100 in the second state when there is not a need for the modular wall 100 to support a significant load. When there is not a need for the modular wall 100 to support a significant load, the second state can be advantageous, for example, to reduce the weight, material cost, and assembly effort associated with the reinforcing inserts 122 and the couplers 124 i-124 l. Furthermore, not all main units 102 within the modular wall need to be in the same state. For example, the main units 102 at some portions (e.g., load-bearing portions) of the modular wall 100 can be assembled in the first state and the main units 102 at other portions (e.g., non-load-bearing portions) of the modular wall 100 can be assembled in the second state.

As shown in FIG. 2, in some embodiments, the first flanges 136 (FIG. 4), the second flanges 138 (FIG. 4), the flanges 200 (FIG. 13), and the flanges 210 (FIG. 14) project downward. In other embodiments, counterparts of the first flanges 136 (FIG. 4), the second flanges 138 (FIG. 4), and the flanges 200 (FIG. 13) can project upward. In these embodiments, the respective positions of counterparts of the base units 110 and the cap units 108 can be swapped. In other words, counterparts of the base units 110 can have the same construction as the cap units 108, and counterparts of the cap units 108 can have the same construction as the base units 110. Furthermore, rather than receiving the first side panel 130 and the second side panel 132 from below, counterparts of the first slots 140 and the second slots 142 can receive counterparts of the first side panel 130 and the second side panel 132 from above.

As discussed above, the main units 102 b, 102 g, 102 k can be arranged to project from the corner portion 116 in two respective directions opposite one another, in two respective directions at a right angle to one another, in three respective directions at right angles to one another, or in four respective directions at right angles to one another and interconnected with other units to form a straight line, an L-shape, a T-shape, or a cross-shape, respectively. Alternatively or in addition, modular walls in accordance with at least some embodiments of the present technology include junction units different than the main units 102. For example, small and large L-shaped junction units can be alternatingly stacked to form two staggered ends suitable for extension by interconnection with the main units 102. Similarly, small and large T-shaped junction units can be alternatingly stacked to form three staggered ends suitable for extension by interconnection with the main units 102. Also similarly, small and large cross-shaped junction units can be alternatingly stacked to form four staggered ends suitable for extension by interconnection with the main units 102.

FIGS. 18a and 18b are top plan views of a small L-shaped junction unit 300 and a large L-shaped junction unit 302, respectively. FIGS. 19a and 19b are top plan views of a small T-shaped junction unit 304 and a large T-shaped junction unit 306, respectively. FIGS. 20a and 20b are top plan views of a small cross-shaped junction unit 308 and a large cross-shaped junction unit 310, respectively. With reference to FIGS. 18a-20b together, the small and large L-shaped junction units 300, 302, the small and large T-shaped junction units 304, 306, and the small and large cross-shaped junction units 308, 310 can be made of square subunits 312 and/or rectangular subunits 314 connected to one another permanently (e.g., by gluing) or semi-permanently (e.g., by bolting) in the illustrated or other suitable arrangements. For example, the square subunits 312 and/or rectangular subunits 314 can interconnected permanently or semi-permanently before the junction units are stacked. The individual square subunits 312 can be the same as or similar to the individual end units 118 of the modular wall 100. Similarly, the individual rectangular subunits 314 can be the same as or similar to the individual main units 102 of the modular wall 100. Alternatively, some or all of the small and large L-shaped junction units 300, 302, the small and large T-shaped junction units 304, 306, and the small and large cross-shaped junction units 308, 310 can have other suitable forms, such as other suitable forms that do not include interconnected subunits.
